Select the machining plane.
Press the "Pole" softkey.
Enter the starting point for the contour in polar coordinates.
Enter any additional commands in G code format, as required.
Press the "Accept element" softkey.
Enter the individual contour elements (see Section "Create contour
elements").
A contour always has to be closed.
If you do not wish to create all contour elements from starting point to
starting point, you can close the contour from the current position to
the starting point.
Press the "Close contour" softkey.
A line from the current point to the start point is created.
You can edit an existing contour by selecting the softkey "Recompile".
The editor cursor must be positioned inside the contour first.
Notice
During recompiling, only the contour elements that have been created
with free contour programming are created again. In addition, only the
texts that were added via the input field "free text input" are
recompiled. Any changes you made directly in the program text are
lost. However, you can still insert and edit free texts afterwards, which
will not be lost.
Further information
The NC code generated by the contour programming in the part
program must never be altered manually. Otherwise recompilation is
no longer possible.
Exception: Insertion of block numbers and masking blocks.
If all contour elements and transition elements have been generated,
save the contour by pressing the "Accept" softkey
